Cervical curettage is the use of a special scraping spoon to scrape the lining of the cervical canal. If there is any abnormality in the cervical canal, it can be diagnosed by taking out the tissue of the cervical canal and doing a pathological examination, which is a common diagnostic method used in gynecology. If there are abnormalities in the cervix during gynecological examination, it is necessary to take tissue from the surface of the cervix for pathological examination, and at the same time to perform cervical curettage. Taking tissue from the cervical canal for pathological examination can make a clear diagnosis, and detect whether there is a lesion, or even cancer of the cervix. If lesions are detected or cervical cancer is present, surgery is necessary, followed by radiotherapy and chemotherapy.
